The JBO Ring Gauges (Go/NoGo) - BSPT (R) are precision tools designed specifically for BSPT (British Standard Pipe Taper) threads, commonly known as R threads. They help plumbers, engineers, and maintenance teams quickly verify that pipe fittings meet BSPT specifications and will seal reliably.

Built with exact dimensions and a focus on repeatable measurements, these gauges streamline thread checks so you can distinguish compliant from non-compliant BSPT connections at a glance. The Go/No-Go design makes inspection fast and consistent, supporting DIN EN 10226 compliance for BSPT threads and the 1 1/4 x 11 size you rely on in many installations.

• Go/No-Go at a glance: Quickly determine whether BSPT (R) threads meet the standard, reducing inspection time and eliminating guesswork so you can proceed with confidence.
• DIN EN 10226 compliant precision: Exact dimensions aligned with the DIN EN 10226 standard ensure reliable fit and sealing across compliant BSPT connections.
• Right-hand BSPT sizing (1 1/4 x 11): Specifically sized for common BSPT fittings so you don’t waste time on mismatched gauges or trial fittings.

Using the JBO BSPT Ring Gauge helps you speed up quality checks, reduce downtime, and improve workflow by giving you an immediate pass/fail read on BSPT threaded joints. It supports consistent results across plumbing, fluid handling, and engineering projects, helping you avoid leaks and rework while delivering reliable, seal-ready connections.
